Application filed I ebruary 11,1897. Serial No. 622,891. (No model.)

To all whom, it may concern: diameter is slightly greater than the diameter Be it known that I, ALEXANDER O. BROW- of the central part of the axle A. The hub NELL, of the city and county of Providence, B also is cut away at its ends to form a thin in the State of Rhode Island, have invented flange and a shoulder, as seen at e in Fig. 2. 55 a certain new and useful Improvement in O C are sleeves screw-threaded and en- Roller-Bearings for the IVheels of Bicycles gageable upon the ends of the axle A, as and other Vehicles; and I declare the followshown. Each sleeve O has an enlarged head ing to be a specification thereof, reference f and a flange g, as shown in Figs. l, 8, and 9. being had to the accompanying drawings.

The holes or sockets n n or vehicle, having its ends screw-threaded. are provided for the reception of a spanner- 45 B is the hub, tubular in form and rotatable. wrench, by which the cap H' can be screwed The hub is screw-threaded upon its ends.

The a vertical rolling bearing to the wheel-hub, Ioo 5o hub B also has the interior fianges c c, each while the balls H H give lateral or endwise with a central circular aperture d d whose bearings, the latter being especially important when the bicycle or vehicle is describing a short curve, in which case the bearing of the hub is both perpendicular to the axle and lateral at the same time.

The cap M or M prevents dampness or dust from reaching the roller, balls, or bearings, and so protects them from being Worn by grit.

I claim as a novel and useful invention and desire to secure by Letters Patent l. In combination with the Wheel of a bicycle or vehicle, a tubular, rotatable hub, an axle having screw-threaded ends, a sleeve on each end of the axle and provided With an annular head, an annular flange extending from said sleeve Within the bore of the hub but surrounding the axle, cages having rollers which are mounted therein and bear on said sleeves, respectively, rings properly slightly protrude outwardly therefrom and means for fastening all said rings together, substantially as set forth.
